The Time Tracking App lets you create and modify time tracking entries that sync with QuickBooks (available for those using QuickBooks Online or QuickBooks Desktop.)
Time tracking entered through Method:CRM will be synced to QuickBooks under the customer you create it for.
When you create or edit a time tracking entry, you will be taken to the following screen:
For those on QuickBooks Online, you will not see Payroll Item. Payroll Item's are synced to and from QuickBooks Desktop only.
From this screen, you can create / edit your time tracking entry.
